React Nested Status
A server-side utility component that passes status codes. Useful to set HTTP status codes based on which components are being rendered.
Built with React Side Effect.
Based (heavily) on React Document Title.
====================
Installation
npm install --save react-nested-status
Dependencies: React >= 0.11.0
Features
- Made for isomorphic apps. Really doesn't have a use without server-side React.
- Does not emit DOM, not even a
<noscript>
; - Like a normal React compoment, can use its parent's
props
andstate
; - Can be defined in many places throughout the application;
- Supports arbitrary levels of nesting, so you can define app-wide and page-specific titles;
Example
Assuming you use something like react-router:
var App = React; var HomePage = React; var ErrorPage = React;
Server Usage
Call NestedStatus.rewind()
after rendering components to string to retrieve the status code given to the innermost NestedStatus
. You can then use this to set your Express (or other web server) status code.
Because this component keeps track of mounted instances, you have to make sure to call rewind
on server, or you'll get a memory leak.
Example
var markup = React;var status = NestedStatus;var html = React; // Expressresstatusstatus;
Thank you
A huge thanks to gaearon for his open-source React Document Title that was easy to understand and modify.
